医学院校解剖实验室内空气中甲醛的测定及防护措施

    Determination and prevention of formaldehyde in the air of anatomy laboratories at medical colleges

    • 摘要: 目的:检测医学院校解剖实验室内空气中甲醛的含量。方法:利用中流量大气采样器采样,采用高效液相色谱法,以2,4二-硝基苯肼的乙腈溶液为吸收液,乙腈水溶液为流动相,经C18反相色谱柱分离,紫外-可见检测器365 nm波长下测定。结果:经测定分析,解剖实验室内空气中甲醛含量高达2.8 mg/m3结论:某医学院校解剖实验室内空气中甲醛浓度是国家规定公共场所标准的23.3倍,师生在此环境中学习和工作是值得关注的。

       

      Abstract: Objective:To determine the formaldehyde concentration in the air of anatomy laboratories at medical colleges.Methods:Medium flow air samplers were used for sampling;high-performance liquid chromatography was adopted;acetonitrile solution with 2,4-dinitrophenyl hydrazine was used as the Absorption liquid,and aqueous acetonitrile as the mobile phase;C18 reversed-phase column was applied for the separation;ultraviolet and visible light purple outside-visible detector was measured at 365 nm wavelength.Results:According to the analysis results,the formaldehyde concentration in the air was as high as 2.8 mg/m3.Conclusions:The concentration of formaldehyde in the air of the anatomy laboratory in a certain medical college is 23.3 times higher than the national standard in public places.It is necessary to ameliorate the environment where teachers and students are working and studying.
